Determine whether each system is LTI, causal and/or stable and with or without memory. Justify answers.

a) y[n + 1] + 4y[n] = 3x[n + 1] - x[n]

b) y[n] = nx[2n]

Solutions

Expert Solution

  • CAUSAL SYSTEM:- System output is independent of future values of input.
  • STABLE SYSTEM:-System output should be BIBO at each and every instant of time.
  • SYSTEM WITH AND WITHOUT MEMORY:-Output is depended only on the present input.

The assumption that a system will operate in a stable environment without risk is not realistic (Sales et al., 2018). Risk is widely classified into disruption and operational risks (Kleindorfer & Saad, 2005; Tang, 2006). Extreme uncertainty and the absence of synchronization between supply and demand are linked to operational risks while circumstances such as labor strikes, terrorist attacks, and natural calamities are related to disruption risks (Lockamy & McCormack, 2010). The probability of human injury or even death is...
